Harbor's courses, starting with Investing Fundamentals. The first lesson is free; the rest is part of Harbor Membership, along with the investor side of Harbor Connect.
The one thing Harbor sells: $19/month or $190/year. It includes every current and future Training Ground course, Compass (an AI guide coming to every lesson), and the investor side of Harbor Connect — founder pitches, interest signals, and introductions made personally. One membership, one bill, everything Harbor makes.
Manage or cancel anytime from the account menu inside Training Ground, or from "Billing" at the top of Harbor Connect — it's the same membership either way.
Compass is Harbor's AI guide coming to Training Ground. It explains concepts and how they apply generally — it never evaluates specific holdings or gives buy, sell, or hold advice.
Harbor's introduction platform for private businesses and private investors. Entrepreneurs put up a Pitch — a short video, their numbers, their story. Investors discover businesses inside industries they actually know, and ask Harbor for an introduction. Every introduction is reviewed and made personally; nothing is automated.
Nothing. Founders publish a Pitch — a video of up to ten minutes, the numbers an investor looks for first, and the case in writing — free, always. Pitch videos are never public: only investors with access to the investor side can watch them, and other founders never can.
It's part of Harbor Membership — $19/month or $190/year — which also includes every Training Ground course. Members get founder pitch videos, interest signals ("I'd invest in this"), and introduction requests that Harbor reviews personally. Cancel any time. If you already hold a Harbor Membership from Training Ground, the investor side is already yours — there is nothing extra to buy.
Two hard filters run first: the industries you chose and your check size. A business outside either never appears in your feed. What remains is ordered by fit: what matters most to you, and above all anything specific you said you're looking for, which carries the most weight because it's in your own words. If you've asked for businesses near you, ones in your state move up. The ordering is rule-based, and every match card names the reasons it surfaced. It decides nothing on its own — every introduction still goes through Harbor.
Harbor reviews it personally. Nothing is sent automatically, no contact information changes hands, and the founder is not contacted at all unless the request is approved. Approved means Harbor sends each of you a link to a private introduction page — who you're meeting, a note from Harbor, and a video room for your first conversation.
Every Pitch and every introduction request gets a decision from Harbor within 48 hours.
Yes. One account can hold a Pitch and an investor profile at once — plenty of Harbor people run a business and back others'. Start with the side that brings you, add the other any time from the account menu, and switch between them freely. The Raise side stays free either way.
A curated shelf of books that have shaped how Harbor thinks, organized by how the ideas actually get used — not by traditional genre.
Yes. Book links are Amazon affiliate links. Buying through one costs nothing extra and helps support Harbor.
